Pretty Print JSON (Formatter, Beautifier)

See more JSON Examples

Demonstrates how to emit JSON in a pretty, human-readable format with indenting of nested arrays and objects. Swift

func chilkatTest() {
    var success: Bool = false

    let json = CkoJsonObject()!

    var jsonStr: String? = "{\"name\": \"donut\",\"image\":{\"fname\": \"donut.jpg\",\"w\": 200,\"h\": 200},\"thumbnail\":{\"fname\": \"donutThumb.jpg\",\"w\": 32,\"h\": 32}}"

    success = json.load(json: jsonStr)
    if success != true {
        print("\(json.lastErrorText!)")
        return
    }

    // To pretty-print, set the EmitCompact property equal to false
    json.emitCompact = false

    // If bare-LF line endings are desired, turn off EmitCrLf
    // Otherwise CRLF line endings are emitted.
    json.emitCrLf = false

    // Emit the formatted JSON:
    print("\(json.emit()!)")
